What Is Synechococcus Elongatus Lysate Filtrate?
Synechococcus Elongatus Lysate Filtrate is a skin care ingredient derived from Synechococcus elongatus, a type of freshwater cyanobacterium often called blue green algae. When these microscopic cells are grown in controlled tanks they are broken open to release their inner contents. The mixture is then filtered so larger cell fragments are removed, leaving a clear liquid rich in peptides, amino acids, vitamins and trace minerals. This nutrient packed filtrate is valued for its ability to support the skin surface.
Interest in this alga began in the 1990s when researchers explored its natural capacity to protect itself from environmental stress. Cosmetic chemists later saw that the same protective molecules could help maintain healthy looking skin, so the lysate filtrate started showing up in skincare labs in the early 2000s. Today suppliers standardise the biomass, lysis method and filtration steps to be sure the final material is consistent and safe for topical use.
Because of its lightweight watery texture the ingredient blends easily into a wide range of formulations. It can be found in serums, moisturisers, eye creams, sheet masks, sun care boosters and anti ageing concentrates, especially those that promise environmental defence or support for the skin barrier.
Synechococcus Elongatus Lysate Filtrate’s Cosmetic Benefits/Uses
In cosmetics Synechococcus Elongatus Lysate Filtrate serves a single key role.
Skin conditioning: the filtrate bathes the skin in hydrating amino acids and peptides that help smooth rough texture and soften the feel of the surface. By supporting the stratum corneum it can make the complexion appear more supple and resilient which is why formulators often pair it with humectants like glycerin for an added moisture boost.
Who Can Use Synechococcus Elongatus Lysate Filtrate
This ingredient plays well with almost every skin type including oily, dry, normal and combination skin. Its lightweight watery feel means it will not clog pores so even those who are prone to breakouts can usually enjoy it. Sensitive skin also tends to tolerate the filtrate because it is free of added fragrance and common irritants. At this time there are no known reasons for eczema or rosacea-prone users to avoid it, though individual tolerance always varies.
Synechococcus elongatus is a microscopic plant-like organism so the lysate filtrate is considered vegan and vegetarian friendly. No animal by-products or animal testing are required to obtain or process the material.
No studies have raised red flags for use while pregnant or breastfeeding, but research on this exact ingredient is limited. This is not medical advice and anyone who is expecting or nursing should double-check any skin care product with a qualified health professional just to be safe.
The filtrate does not make skin more sensitive to sunlight and it can even be included in day creams designed to shield the skin from environmental stress. There are no known ingredient conflicts, so it layers smoothly with acids, retinoids, peptides and sunscreen filters.
Potential Side Effects/Adverse Reactions
Side effects from Synechococcus Elongatus Lysate Filtrate vary from person to person. The points below list potential reactions, but most users will not run into these problems when the ingredient is manufactured and used correctly.
- Redness or flushing some very sensitive skins may notice temporary warmth after application
- Mild stinging a short-lived tingling can occur, especially on compromised skin barriers
- Itchiness rare histamine-type reactions have been reported with algae extracts
- Contact dermatitis in extremely uncommon cases an allergic response can lead to patches of irritation or small bumps
- Eye irritation if the product accidentally gets into the eyes it can cause watering or discomfort until rinsed out
If any of these issues appear stop using the product and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0 / 5
Synechococcus Elongatus Lysate Filtrate is an almost entirely water based extract that contains trace nutrients but virtually no oils or waxes that could block pores. Its molecules are small and disperse quickly across the skin rather than sitting in follicles, so the chance of triggering comedones is extremely low. This makes it suitable for acne prone or breakout prone skin.
The only caveat is the finished product formula. If the filtrate is blended with heavy butters or occlusive silicones in a cream, the overall product could still cause congestion even though the lysate itself will not.
Summary
Synechococcus Elongatus Lysate Filtrate is used mainly for skin conditioning. Its mix of peptides, amino acids and trace minerals helps smooth texture, support hydration and reinforce the skin surface so it feels softer and more resilient. These benefits come from the algae’s natural stress defending compounds that are carried into the filtrate after cell lysis.
The ingredient is gaining steady but still modest popularity in serums and barrier repair products, especially those marketed for urban stress or blue light protection, yet it has not reached mainstream status like hyaluronic acid or niacinamide.
Current data show the filtrate is generally safe with a very low risk of irritation or pore blockage. As with any new cosmetic ingredient it is smart to patch test a product on a small area first to rule out individual sensitivities before applying it to the entire face.
